Writer-director Paul Weitz may joke about the two people who will tune into his commentary with star Topher Grace, but in truth the pair make for very good company indeed.

Writer-director Paul Weitz may joke about the two people who will tune into his commentary with star Topher Grace, but in truth the pair make for very good company indeed.

Both are very light with a quip and compliment to cast and crew, and their patter displays the same comedic warmth as Weitz’s story about a father coping with a younger boss who dates his daughter. The same jokiness percolates through much of the extras, designed so that each segment spells out “Synergy,” the movie’s original title. The concept doesn’t always work — insights by the Maloof brothers on what it means to be a successful businessman seem especially jarring — but the extras have their charms, including a tour of Gotham locations and the edit bay. For his part, Dennis Quaid was gratified to be a tad young for the part. “I take solace in the fact they had to age me up to play it.”
